This research paper investigates the technical feasibility, system requirements, performance characteristics, and potential for optimization of an industrial heat pump in a district heating system, using the Modelon Impact platform. The study aims to provide a comprehensive understanding of the benefits and limitations of using cloud-based simulation platforms for the design and analysis of indust
Syftet med vårt arbete är att identifiera vilka metoder och verktyg som finns kopplade till mental träning samt hur lärare kan använda sig av dessa i musikundervisning. Vår första forskningsfråga handlar om hur mental träning används idag, vilket behov som finns och vilka metoder som används. Vi är intresserade av att ta reda på hur aktiva musiker använder sig av mentala redskap samt ta del av der
The purpose of this study is to design and investigate a pulsating heat pipe device (PHP). A PHP is a two-phase flow heat transfer device which can handle high heat fluxes with passive internal flow. It is made of a continuous loop serpentine, partially filled with a working fluid that can cool systems, such as electronic devices. It differs from a conventional heat pipe device in design and opera
With an ongoing energy crisis in Europe and an ever-evolving political climate where the environmental impacts of industries are regarded as a top priority, the topic of energy efficiency is high on everyone’s agenda. Mathematical optimization of energy consumption requires a model of the problem at hand. In this thesis linear regression is compared with the gradient boosted trees method and a neu
Cities face multiple social-ecological challenges, which nature-based solutions (NBS) promise to address. Strategies to mainstream NBS have only achieved partial success, hence recent studies suggest that inner dimensions - mindsets and transformative capacities - must be mainstreamed simultaneously. This study investigates municipal employees' engagement with inner dimensions, its impact on s
The future of agriculture depends on healthy soils, but soils are degrading within dominant agricultural systems, also in Denmark. Pioneer farmers seek a sustainable transition towards soil-centered management. However, reinforcing feedback loops in current agriculture is blocking such a transition. Founded in emancipatory social science and critical utopian action research, this thesis, in collab
Att under sin uppväxt bli utsatt för mobbning av jämnåriga kan innebära långtgående negativa konsekvenser för hälsa och mående för den utsatta. Fortfarande är det många barns vardag att vara utsatta för mobbning. Mobbningen sker idag inte enbart i skolmiljö utan även på nätet. Syftet med studien var att undersöka föräldrars syn på deras möjlighet att agera vid sitt eget barns utsatthet för skol- eDuring childhood and adolescence, being subjected to bullying by peers can have far-reaching negative consequences for the health and well-being of the victim. Unfortunately, many children continue to experience bullying, which now occurs not only in school environments but also online. The purpose of this study was to explore parents' perspectives on their ability to respond when their own ch
Regularly described as hotspots for marine life, seamounts are important foraging grounds for marine predators. In surface waters over seamounts, diel vertically migrating organisms can be aggregated, making seamounts potentially attractive and profitable food sources for predators such as seabirds. Still, the potential association between seabirds and seamounts has seldom been described and littl
Bakgrund: Samtliga Svenska vattenkraftverk och dammar ska under en tjugoårsperiod få moderna miljövillkor inom den nationella planen för omprövning av vattenkraft (NAP). Nio svenska kraftbolag finansierar tillsammans, genom Vattenkraftens Miljöfond Sverige AB (Fonden), kostnader som uppstår i samband med miljöåtgärder inom NAP. Tidigare studier visar att det finns en anlockningsproblematik vid de
This paper analyzes the set of political skills that middle managers use to navigate the aerospace industry. The current study considers Mintzberg’s (1985), Ferris et al.’s (2007), and Treadway et al.’s (2005) conceptualization of organizations as political arenas, will, and skills. Thus, it constitutes a theoretical base to create a new tailored political skills framework that could help aerospac
Som en del i utvecklingen mot grönare och miljövänligare processer, samt ett behov av ytterst specifika reaktioner, vill AAK AB utvidga sin användning av lipaser i sin produktion av strukturerade triacylglyceroler (STAGs). AAK vill bygga upp ett bibliotek av utvärderade lipaser. Syftet med detta examensarbete är att bidra till detta bibliotek genom att karakterisera en grupp kommersiellt tillgänglAs part of a switch towards more green and environmentally friendly processes, together with a need for highly specific reactions, AAK AB wants to broaden their use of lipases in the production of structured triacylglycerols (STAGs). AAK are working on creating a lipase library where several lipases are evaluated, this master thesis aims to contribute to this lipase library by characterizing a sel
A study has been created to develop a method quantifying the active pharmaceutical ingredient (API) nicotine in tablets with near infrared (NIR) spectroscopy using chemometrics. The current technique, liquid chromatography (UHPLC), used to determine the nicotine content in tablets is time consuming and require sample preparation. NIR spectroscopy is non-destructive and the implementation of NIR sp
This thesis deals with the characterization of the approved inner tracker upgrade of the ALICE experiment involving an innovative and ultra-thin silicon detector with a cylindrical geometry. During this thesis work, Monolithic Active Pixel Sensors (MAPS) were studied for the first large-scale prototype of the upgrade, together with a sensor of the same technology with smaller size. Properties of t
Leukemia is the most common type of cancer in children, with B-cell acute lymphocytic leukemia (B-ALL) being a common type in both children and adults. Different types of treatments are available, such as chemotherapy, stem cell treatment and immunotherapy. However, a recurring problem is relapses, with the survival rate after relapse being very low. In combating this issue new methods have been d
This project uses proton-proton collision data from the ALICE experiment at CERN to investigate the differences between three ways to classify events, known as event shape classifiers. The event shape classifiers that were investigated are RT , spherocity and flattenicity. The motivation behind this is the consistent use of these classifiers to select events when investigating the heavy-ion like
Visualization of the molecular and morphological complexity of organs can be achieved through advanced imaging techniques. Imaging has increased our understanding of disease, pathology, and mechanisms. Classic 2D-imaging modalities provide detailed information at a microscopic scale and while valuable, it lacks the ability to explore the spatial resolution of disease mechanisms such as the locatio
Cultured meat production presents a sustainable solution to the environmental, ethical, and antibiotic-related challenges of conventional meat production. This master’s thesis explores the pivotal role of cell culture media in cultivating meat, emphasizing the importance of developing cost-effective and sustainable alternatives to fetal bovine serum (FBS). The study aims to extract functional prot
